As we have noted in the beginning of the paper, our motivation was to compute main characteristics of the dual viscous fluid within the Membrane Paradigm before starting analogous computations on the Gauge/Gravity Duality side. Mainly, our focus was on computation of the shear viscosity due to importance of this quantity for the Gauge/Gravity Duality. Though we have recovered the classical result of the old Membrane Paradigm, which coincides with the KSS bound coming from the AdS/CFT correspondence, it still looks enigmatic, how these different approaches, strictly speaking unrelated to each other (see [1]}, [2]} for details), may lead to the same answer. For example, the 4D bulk viscosity results obtained from the AdS/CFT are no longer so unambiguous, as it comes from
the following simple result [3]}, [4]}:
\(\frac{\zeta }{\eta }\ge 2\left(\frac{1}{3}-c^2_s \right).\)
